Syntax-free computation / Format-free computation:

Syntax-free (aka format-free) math computation is a novel software technology that allows users to input equations as in a notebook free of computational formats; the software program works out how to complete computations for these equations. This will not only produce prompt solutions, but also make users more concentrated on the issue itself without distraction from knowledge of computational format requirements. VisualLab demonstrates such a technology is achievable.

Graph digitizing:

Graph digitizing, aka plot digitizing, curve digitizing is a software technology that reads the graph shown in a figure/picture, converts it to x-y numbers so that mathematical analyses can be carried out for the graph. Note that figure/picture is actually already in a digital form; graph digitizer is actually a software tool for recognizition of graphs in the figure/picture.

Area size computation:

Area size computation refers computation of area size enclosed by any select set of points. One can freely define and select data set consisting of no less than 3 points, its enclosed area size is then computed. This functionality is particularly useful to e.g. curve analysis in analytical chemistry, calculation of maps or drawings.

Formula calculator / formula evaluator:

A formula calculator, aka expression calculator, formula evaluator, is a calculator that can perform calculations for a math formula or expression by a single button action to obtain final results.

Curve fitting:

Curve fitting is a process of constructing a mathematical function, which has the best fit to the curve consisting of a series of data points.

Linear equations:

Linear equations are algebraic equations in which each term is either a constant or the product of a constant and a single variable. Simultaneous linear equations are a set of two or more linear equations, each containing two or more variables whose values simultaneously satisfy all the equations in the set, with number of variables being equal to or less than the number of equations in the set.

Non-linear equations:

Nonlinear equations, a.k.a. nonlinear system, are algebraic equations that are not linear equations. Simultaneous nonlinear equations are a set of equations in which at lerast one of them is nonlinear equation. Typical example of nonlinear equations is a polynomial of degree higher than one.


A polynomial is an expression consisting of variables and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables. Examples of polynomial include quadratic equations.

Transcendental equations:

A transcendental function is an analytic function, in which its variable cannot be expressed in terms of a finite sequence of the algebraic operations of addition, multiplication, and root extraction.

Normal distribution:

A normal (or Gaussian or Gauss or Laplace Gauss) distribution is a bell shaped continuous probability distribution for a real-valued random variable.

Binomial distribution:

A binomial distribution is a discrete probability distribution. For any boolean valued outcomes, if probability, p, represents the probability of positive outcome, q = 1 - p would be the probability of negative outcome. Its probability mass function describes the probability of getting exactly k positives in n independent Bernoulli trials.


A t-test, also known as Students t-test, is a test to determine if the difference between the means of two groups is statistically significant, or to determine if the mean of a group is statistically significant from a given value.


ANOVA (analysis of variance) is a technique in statistics. It is used to analyse the variation among and between groups to check if the means of two or more groups are significantly different from each other.
